Radioactive dating assumptions
To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating.
Radiometric dating is largely done on rock that has formed from solidified lava.
Despite very impressive and powerful measurement and characterization tools, physical and chemical analysis methods, the dating of rocks by using radioactive elements depends on very basic assumptions.
The significance and relevance of these assumptions have not been demonstrated.
An isotope is one of two or more atoms which have the same number of protons in their nuclei, but a different number of neutrons.
Radioisotopes are unstable isotopes: they spontaneously decay (emitting radiation in the process -- thus making them radioactive).
By measuring how long it takes for an unstable element to decay into a stable element and by measuring how much daughter element has been produced by the parent element within a specimen of rock, scientists believe they are able to determine the age of the rock.
This belief is based upon three significant assumptions.
All radiometric dating methods rely upon important assumptions usually not mentioned by evolutionists... rely on these few basic assumptions: - Beginning Conditions Known - Beginning Ratio of Daughter to Parent Isotope Known (zero date problem) - Constant Decay Rate - No Leaching or Addition of Parent or Daughter Isotopes - All Assumptions Valid for Billions of Years - There is also a difficulty in measuring precisely very small amounts of the various isotopes Absolute dates do not necessarily tell us precisely when a particular cultural event happened, but when taken as part of the overall archaeological record they are invaluable in constructing a more specific sequence of events.In fact, the first radiochronology assumptions were adapted to fit the stratigraphic scale used by geochronologists of the end of the 19th century.Radiometric dating methods are calibrated against the geologic column, which is a relative timescale based on evolution theory and naturalism.They continue to decay going through various transitional states until they finally reach stability. It will spontaneously decay until it transitions into Lead-206 (Pb206).The numbers 238 and 206 represent these isotopes' atomic mass.
